What the data for this category looks like
The daily documents for this category include maintenance plans, patrol logs, defect disposal reports, road construction permits, road property damage compensation forms, and similar items. Data sources include highway maintenance management systems, bridge and tunnel monitoring systems, road administration patrol systems, and traffic flow monitoring data. Data updates daily. Document fields typically include facility location, operation time, approval number, disposal result, and similar items. Some documents link to physical asset numbers and maintenance budget entries. The data structure primarily mixes structured forms and unstructured text.
What constraints do these characteristics impose on the source citation and traceability link
Data for this category updates daily. This means the citation and traceability link must support daily synchronized data updates, so retrieval results match the latest maintenance and road administration information. Documents mix structured forms and unstructured text, and include unique identifier fields such as facility numbers and approval numbers. This requires precise association of corresponding fields during traceability to avoid information confusion across documents. Some documents link to physical assets and budget entries, so the association between data must be retained during traceability. This ensures cited sources can be fully traced back to original business documents.
How to configure the settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
quoteMaxToken | 800–1200 token | Matches the average text length of a single document for this category, ensuring complete citation of original content |
responseData | Enabled | Required to return unique identifiers such as approval numbers and facility locations from documents to support traceability verification |
detail | Enabled | Retain complete content fragments of original documents to avoid truncation of critical road administration approval or disposal information |
| Single search limit | Top 5–7 results | Covers retrieval needs for multiple document types including daily patrol logs and road construction permits |
| Chunk overlap length | 50–80 characters | Adapts to chunk linking for mixed-structure documents, preventing key fields from being split across different chunks |
Three common configuration mistakes
- Issue: Generated responses do not directly use the original answer from the knowledge base Q&A pairs, instead generating new content. Cause: The
quoteMaxTokenparameter was not adjusted based on the length of the Q&A pair text, resulting in overly long Q&A pairs being truncated or not fully retrieved. - Issue: Retrieval results do not display associated original document identifiers in the response. Cause: The
responseDataconfiguration was not enabled, resulting in only text fragments being returned and key traceability information such as approval numbers and facility locations being lost. - Issue: Unable to select variables for knowledge base retrieval results in workflow code nodes. Cause: The workflow association function was not enabled in the knowledge base configuration, or the output of the retrieval node was not correctly bound to the corresponding variable.
How to confirm the configuration is correct
Reference only; verify against the target FastGPT release and deployment documentation.
- Initiate a query related to road construction permits, and check whether the response contains the approval number and facility location fields of the corresponding document.
- Import a complete maintenance Q&A pair, initiate a query, and confirm that the response content exactly matches the original answer in the knowledge base.
- Attempt to call the knowledge base retrieval result variable in the workflow node, confirm that the first retrieval result can be normally selected and output.
- View the data source synchronization log, confirm that daily maintenance and road administration data has completed automatic synchronization updates.
